Slots or holes or there for heat, not raw stopping power. Stopping shorter comes mostly from better tires, although a larger caliper/rotor can also generate more leverage. Pad compound is also a significant factor, assuming they are at the right temperature
Slotted/cross drilled also eats pads faster. And if you get cheap slotted/cross drilled rotors that are poorly made, they will be more prone to cracking. IIRC high end ones are CAST with the holes or slots in them, so they're strong; drilling afterwards can make it less structurally sound, esp if done poorly.
I'm guessing you're driving around town and dont need anything but an OEM replacement.
Nismo Z's don't come with cross drilled rotors because Nissan wants the brakes the last, and the nismo isn't are hardcore track focused as you think. It's not a GT3 or something, its a 40k sports car, not 100k.

Well considering I was in a 2005 350z ...non nismo ...there was much better stopping power and cut my stopping distance down at least 25% I would call that "dramatic" .... taking all factors in account of old worn pads/rotors which had chatter while stopping .....and to be more accurate ...I stated I seen a dramatic "improvement" .....meaning overall from where I started .....that's why I asked the question based on a new nismo stock vs slotted/drilled if there would be a "improvement" ....... a simple no would have done .......and never assume how anyone drives there car based on a question
